Plexus Acquires Integrated Environmental Management, Inc.

Plexus Scientific Corporation announced today that it has acquired Integrated Environmental Management, Inc. (IEM), a SBA-registered Woman Owned Small Business, headquartered in Gaithersburg, MD, and with offices in Ohio. The transaction closed on January 1, 2015.
Plexus Scientific Corporation (Plexus) is an employee-owned small business founded in 1985 and headquartered in Alexandria, VA. Plexus offers environmental remediation services to its Department of the Army, Department of the Air Force, U.S. Army Corps of Engineers, and commercial clients nationwide, as well as environmental, sustainability, energy, and safety consulting services to its Federal clients. Plexus also provides business and information technology solutions that help Federal agencies improve their performance.
Founded in 1994, IEM provides strategic radiation management, nuclear services (including assessment, decontamination, decommissioning, and remediation), radioactive waste management and disposal, and senior-level radiation-related consulting to hundreds of commercial and government clients. In the commercial sector, IEM works with companies in the chemical, pharmaceutical, nuclear, oil/gas, manufacturing, real estate and banking, pulp and paper, insurance underwriter, research/development, consumer products and metallurgical industries, as well as with public utilities and organizations that provide medical diagnosis and treatment. In the government sector, IEM’s experience includes work for the U.S. Departments of Energy, Defense, Agriculture, Labor, and Commerce; the U.S. Nuclear Regulatory Commission; the U.S. Army Corps of Engineers; Federal Occupational Health; the Federal Bureau of Investigation; and numerous State, county, and local agencies. IEM holds a comprehensive Radioactive Material License from the Maryland Department of the Environment, which allows it to provide an extensive array of radiological services to its clients nationwide.
Together, Plexus and IEM present a great strategic fit for both companies’ lines of business. IEM’s broad radiological experience is a perfect addition and complement to Plexus’s current catalogue of environmental remediation services, environmental consulting, sustainable solutions, business solutions, and vice versa. Both companies share the same affinity and passion for high quality work, great customer satisfaction, and employee loyalty, as evidenced by the fact that both have operations that are certified to the ISO 9001:2008 international quality standard.
Beginning on January 1st, IEM began conducting business as “IEM, A Plexus Company,” and its staff continues to serve the needs of existing clients as the new company structure solidifies. “We’re excited to join forces with IEM,” said Jackie Cain, Chair of Plexus’s Executive Management Team. “It’s a great strategic and cultural fit for both companies and will allow Plexus to offer a wider array of services to both of our client bases.” Carol Berger, President of IEM, echoed these sentiments, “We have been relying on Plexus’s non-radiation-related expertise for a number of years now, and we see even better opportunities for growth and improvements in our delivery systems now that we are one team. This is the perfect organization for serving clients who face both radiological and other environmental challenges.”
